Intel (INTC), the world's largest semiconductor company, has been facing pressure due to the declining PC market. Though the company has captured a ~85% market share of the PC microprocessor market, the stock has been range bound in the last few years. Intel is now targeting the fast growing smartphone and tablet semiconductor space. Intel has started to increase its focus on mobile products, which are growing much faster than the PC and laptops.
Intel's new processors are focused on reducing power consumption, which is critical for success in the mobile devices space. Intel's new Haswell chips for PCs/laptops are ready to ship in the 2nd quarter of 2013, and they will hit the ball out of the park in terms of battery performance. The Haswell powered ultrabooks and notebooks will give the same battery performance as the iPads, which should help in slowing down the cannibalization by tablets.
What this all means to MSFT? IMO, it is a huge gain.
